Whenever it is ascertained by the Director or the City Solicitor that a lesser sum may be collected than the total taxes, penalties, and interest due, the City Solicitor shall be authorized to:compromise the claim; accept the lesser sum on behalf of the Director; and issue a release of the claim or satisfaction of the judgment as though the same had been paid in full. Such compromise is authorized only in such cases where the City Solicitor and the Director concur that the full amount would be uncollectible. City Code, 1976/83, art. 28, §88 Ord. 86-687
